We have been building and tuning record-setting GenIII Hemis since 2006. With 40 years of automotive

10/14/2026

This wild supercharged 3.6 Jeep on 40s had a list of tuning issues that needed to be resolved. The Jeep ran poorly, would not shift, and was very sluggish to accelerate. Unfortunately, the tune that was in the Jeep was quite terrible and was certainly causing all the issues described to us.

We started from scratch and in a couple hours got it running and shifting excellently. Our customer took it for a short drive around the area and loved it! Glad we could get it running right for him after all he had been through with his previous attempts elsewhere.

OST high compression 426 Hemi assembled and ready to go in the car. With our Big Daddy camshaft and the manual transmission, this will be a really fun car to drive and make awesome power!

Another one fixed up so the owner can finally enjoy it!

This Challenger RT arrived with a very poor tune that prevented the owner from being able to drive or race the car without issues. The transmission tune had also damaged the transmission and it would not complete a 3-4 WOT shift. We tried to tune around the transmission issue but in the end the trans simply needed to be replaced. The fuel system was also not up to the task and pressure was dropping at high RPM.

We pulled the car off the dyno, waited for a slot in the schedule, and got to work. The trans was rebuilt and upgraded by SOUTHERN HOTROD, LLC, our high stall converter from Perfect Converter installed, as well as a FORE fuel system. We then dropped the pulley size to a 3.25 and added E85 to the tank.

Not only did the car gain 135whp and have the fuel system and transmission to handle it, but it can be started, driven, raced, and enjoyed. Looking forward to dialing this one in at the track!

The crazy things that come in now and again for tuning! This was a Holley Sniper equipped rat rod that we were able to straighten out.

We recently completed this 3.0 Whipple install for a great customer! He also requested some gauges inside and supplied a slick 3D printed mount.

At 7lbs of boost, this is a super fun truck to drive. It was tough handing the keys back!
